FIELD

The present specification relates generally to endoscopes, and more specifically, to a stand for supporting one or more endoscope monitor screens. The present specification also relates to a monitor stand cart that can be used to carry endoscopic equipment and may be transported in a medium sized vehicle.

BACKGROUND

An endoscope conventionally comprises an elongated tubular shaft, rigid or flexible, having a video camera and/or a fiber optic lens assembly at its distal end. Various surgical tools may be inserted through a working channel in the endoscope for performing different surgical procedures. Endoscopes, such as colonoscopes, that are currently being used, typically have a front camera for viewing the internal organ, such as the colon, an illuminator, a fluid injector for cleaning the camera lens, and a working channel for insertion of surgical tools, for example, for removing polyps found in the colon. Often, endoscopes also have fluid injectors (“jet”) for cleaning a body cavity, such as the colon, into which they are inserted. The illuminators commonly used are fiber optics which transmit light, generated remotely, to the endoscope tip section.

Endoscopes having multiple viewing elements, such as cameras, generate multiple video feeds which require display. These video feeds are typically generated in native or standard square formats of aspect ratios 4:3 or 5:4. Such native square formatted video feeds when displayed on widescreen or rectangular monitors cause ‘pillar-boxing’ if not modulated to fit the widescreen but result in unacceptable image/video distortion if modulated to fill the entire widescreen.

Hence, the video feeds generated by a plurality of viewing elements of an endoscopic tip are processed such that the video feeds can be displayed appropriately on a plurality of advantageous configurations of widescreen monitors. Usually three monitors (a left, a center and a right side monitor) are placed side-by-side or contiguously. In some cases, the three monitors together provide a panoramic view based on an overlap between fields of view of the three viewing elements (front-looking and the two side-looking viewing elements).

There is need for an arrangement for supporting the monitors so that they may be viewed by an operating physician with ease.

In an embodiment, the monitors are supported by an isolation transformer that minimizes leakage current that may be caused by the monitors. The isolation transformer transfers electrical power from an alternating current (AC) power source to the monitors while isolating said monitors from the power source. This serves to suppress electrical noise between the monitors and protect against electric shock. In an embodiment, the monitor stand frame 106 is attached with an isolation transformer assembly stand 108 for supporting an isolation transformer and also providing a base for balancing the weight of the monitors 102 supported by the monitor arm assembly 104. The isolation transformer assembly stand 108 has a top surface, a bottom surface, a front side and a back side. Further, a groove is provided on the back side for attaching the monitor stand frame 106. In an embodiment, the isolation transformer is attached to a bracket that is assembled with screws onto the monitor stand frame 106.

Further, in various embodiments, isolation transformer assembly stand 108 comprises at least one wheel, and preferably two front wheels 110 and two rear wheels 112, mounted on the bottom surface of the isolation transformer assembly stand 108 for mobility of the monitor stand 100. In the embodiment shown in FIGS. 1A and 1B, two front wheels 110 and two rear wheels 112 are provided on an underside of the isolation transformer assembly stand 108. The front and rear wheels 110, 112 enable the monitor stand 100 to be mobile. The monitor stand 100 may be moved to a desired location even during operation of the monitors 102. In an embodiment, only the rear wheels 112 are provided with a locking mechanism for fixing the position of the monitor stand 100 in a desired location while in another embodiment, both the front and rear wheels 110, 112 are provided with a locking mechanism.

FIG. 2A illustrates the monitor arm assembly 200, in accordance with an embodiment of the present specification. The monitor arm assembly 200 has an arcuate shape having a middle or center portion 202, that is substantially straight, a first end or left portion 204, that is raised relative to the middle portion, and a second end or right portion 206, that is raised relative to the middle portion. In an embodiment, the monitor arm assembly is approximately 1209 mm long and the two end portions 204, 206 are raised, or bent, at an angle of approximately 20 degrees from the plane of the straight portion 202. Also, in an embodiment, the two end portions 204, 206 are raised, or bent, to a height of approximately 142 mm from the plane of the straight portion 202. One monitor is supported by each of the first end portion 204, the second end portion 206 and the middle straight portion 202.

FIG. 2B illustrates another view of the monitor arm assembly 200. Three monitors may be mounted on the monitor arm assembly 200. In an embodiment, one monitor may be mounted on the first end or left portion 204 by means of a left bracket 208, a second monitor may be mounted on the straight or center portion 202 by means of a center bracket 210 and a third monitor may be mounted on the second end or right portion 206 by means of right bracket 212. The brackets 208, 210 and 212 fix the monitors onto the monitor arm assembly 200 in such a way that the edges of all the monitors are aligned with each other. In various embodiments, the brackets 208, 210, 212 are positioned proximate a center of each corresponding portion 204, 202, 206. The brackets 208, 210, 212 are horizontally slidable and fixable along said center of each portion 204, 202, 206, as described in further detail with respect to slot 214 of FIGS. 2C and 2D. Horizontal movement of the brackets 208, 210, 212 proximate the center of each portion 204, 202, 206 allows for edge-to-edge alignment of monitors of varying sizes. When a left monitor is attached to the left bracket 208, which is affixed to the left portion 204, a right edge of said left monitor is flush with a left edge of an attached center monitor, said center monitoring being attached to the center bracket 210, which, in turn, is affixed to the center portion 202. In the same manner, when a right monitor is attached to the right bracket 212, which is affixed to the right portion 206, a left edge of said right monitor is flush with a right edge of the attached center monitor.

FIG. 2C illustrates the monitor arm assembly 200 with a magnified view of the first end portion 204. FIG. 2D illustrates a further magnified view of the first or left end portion 204. In various embodiments, the monitor arm assembly has a height dimension h_(a) of approximately 2 inches and a width dimension w_(a) of approximately 1 inch. As shown in FIGS. 2C and 2D, the end portion 204 comprise a slot 214. The left bracket 208 comprises a protruding pin 216 which is inserted into the slot 214, as shown, and is used for securely attaching the bracket 208 to the first end portion 204 by means of screw 218. In various embodiments, a height dimension h_(s) of the slot 214 varies from 5.0 millimeters to 10.0 millimeters and, in one embodiment, is preferably 8.2 millimeters, thereby allowing an M8 stud of the bracket 208 to slide into the slot 214 with ease. In various embodiments, a left edge of the slot 214 varies from approximately 120.0 millimeters to 140.0 millimeters and, in one embodiment, is preferably 130.9 millimeters, from a left end of the left end portion 204. In various embodiments, a length dimension l_(s) of the slot 214 varies from 25.0 millimeters to 50.0 millimeters and, in one embodiment, is preferably 38.2 millimeters, to allow for sliding and positioning of the bracket 208 along the length of the slot 214. This feature enables the monitor arm assembly 200 to accommodate monitors of varying sizes while still allowing for flush edge-to-edge positioning of the monitors, thereby providing a substantially seamless panoramic view of the monitor screens. Right bracket 212 is securely attached to the second or right end portion 206 in a similar manner. In an embodiment, bracket 210 comprises two portions, namely a smaller bracket fixed to the monitor and a bigger bracket attached to the straight portion 202. Both the smaller and the bigger bracket have the same shape/angle on a side rib for better guidance and the bigger bracket comprises a thumb screw that locks the smaller bracket to the straight portion 202.

FIG. 2E illustrates a magnified view of a left portion 204 of the monitor arm assembly 200 attached with a left bracket 208 for coupling with a monitor, in accordance with an embodiment of the present specification. As shown, screw 218 holds the bracket 208 in place. Mating areas 220 eliminate rotation of the monitor with respect to the monitor arm assembly 200 and fix the monitor in position. In an embodiment, flanges 223 of the bracket 208 which are parallel to the monitor arm assembly 200 eliminate rotation of a monitor held by the monitor arm assembly 200 and fixes its position. The flanges 223 extend over top and bottom edges of the monitor arm assembly 200 and prevent rotational movement of the bracket 208 about said monitor arm assembly 200. Minimal clearance between the flanges 223 of the bracket 208 and the monitor arm assembly 200 prevents the bracket 208 from rotating, as upon rotation the flanges 223 would hit the monitor arm assembly 200 stopping the rotation.

FIG. 2F illustrates a front view of the monitor arm assembly 200, in accordance with an embodiment of the present specification. The straight or center portion 202 comprises six aluminum spacers 222, 224, 226, 228, 230, 232, and two inserts 234 flush with a front surface of the straight portion 202 of the monitor arm assembly 200. In an embodiment, the distance between the two inserts 234 is 35 mm. Also in an embodiment, a first distance between spacers 222 and 232 is approximately 214.20 mm, a second distance between spacers 224 and 230 is approximately 134.20 mm, and a third distance between spacers 226 and 228 is 88.90 mm. In an embodiment, each of the spacers has an internal diameter of approximately 5/16 inches and a length of approximately one inch. In an embodiment, the spacers are welded flush to the surface of the monitor arm assembly. Referring to FIGS. 1A, 1B, and 2F simultaneously, in various embodiments, the inserts 234 are used to attach the monitor stand frame 106 to the monitor arm assembly 200 in a pivot like arrangement, enabling rotation of the monitor arm assembly 200 coupled with the monitors in a user desired direction with respect to the monitor stand frame 106. In various embodiments, the monitor arm assembly is made of aluminum and has a low weight. The spacers 222, 224, 226, 228, 230, 232 strengthen the structure of the monitor arm assembly. Further in various embodiments, the monitor arm assembly is a hollow structure, and hence, tightening a screw through the structure would cause the screw to bend the assembly internally. Therefore, the use of spacers 222, 224, 226, 228, 230, 232 ensures secure attachment of the monitor arm assembly with the monitor stand frame 106 without causing any damage to the monitor arm assembly.

FIG. 2G illustrates a magnified view of a monitor arm assembly 200 with monitors 251, 252, 253 attached thereto coupled to a monitor stand frame 246, in accordance with one embodiment of the present specification. A center monitor 252 is attached to the monitor arm assembly 200 via a center mounting bracket 210. The center mounting bracket 210 also serves to couple the monitor arm assembly 200 to a pivoting mechanism 240 of the rigid monitor stand frame 246. The pivoting mechanism comprises a pivoting bearing 241 which is coupled, via a pair of nuts and bolts 242, to the center mounting bracket 210. The bolts pass from the center mounting bracket 210 through the inserts (234 of FIG. 2F) of the monitor arm assembly 200 and are fixed to the pivoting bearing 241 by the nuts, thereby securely attaching the monitor arm assembly 200 to the pivoting assembly 240. The pivoting assembly 240 also includes a pivoting post 243 which is attached via a pivoting mechanism bracket 245 to a center frame portion 247 of the monitor stand frame 246. The center frame portion 247 extends from a top end of the monitor frame stand 246 to a bottom end of the monitor frame stand 246. The pivoting bearing 241 is positioned on and rotatable about the pivoting post 243. A locking ring 244 attaches to the pivoting post 243 above the pivoting bearing 241 to prevent the pivoting bearing 241, and attached monitor arm assembly 200, from slipping off the pivoting post 243. Once the pivoting mechanism 240 has been assembled, a user may pivot the monitor arm assembly 200 in a horizontal plane relative to the monitor stand frame 246 by applying slight pressure to either side of said monitor arm assembly 200. The pivoting bearing 241 is free to rotate about the pivoting post 243, which allows all three monitors to be pivoted in the same direction/manner concurrently. Additionally, in some embodiments, the pivoting mechanism bracket 245 may be slid vertically along the center frame portion 247 of the monitor stand 246 to adjust the height of the monitor arm assembly 200. In one embodiment, a locking mechanism is included for locking the pivoting mechanism bracket 245 at a fixed vertical position on the center frame portion 247.

In various embodiments, the present specification provides a light weight and compact monitor stand that may be transported in a medium to small size vehicle. Further, in various embodiments, the monitor stand may be dismantled by detaching the monitor stand frame from the isolation transformer base stand and the monitor arm assembly.

In an embodiment, the monitor stand of the present specification may be folded and/or dismantled for transport. FIG. 3A illustrates an embodiment of the monitor stand in an extended and assembled position. The monitor stand 300 comprises a first fixed rigid stand frame or spine portion 302 and a second extendable stand frame portion 304.

In various embodiments, the monitor stand 300 includes a locking mechanism for fixing the extendable frame portion 304 at a specific position within and relative to the rigid frame portion 302. In various embodiments, the locking mechanism comprises a lever or button that is pressed by a user, allowing free movement of the extendable frame portion 304. When the lever or button is released, the extendable frame portion 304 becomes locked in place.

A monitor arm assembly 306 is coupled with an upper end of the second extendable stand frame portion 304 via a coupling component 305. The coupling component 305 enhances the collapsibility of the monitor stand 300 in two ways: it allows for detachable coupling of the monitor arm assembly 306 from, and rotation relative to, the second extendable stand frame portion 304; and, it is vertically slidable within said second extendable stand frame portion 304 from a first, top position relative to the second extendable stand frame portion 304, as depicted in FIG. 3A, to a second, bottom position relative to the second extendable stand frame portion 304, as depicted in FIG. 3B, and any position therebetween. The coupling component 305 is further described with reference to FIGS. 4D and 4E.

When in an assembled configuration for supporting one or more monitor screens, the entirety of the monitor arm assembly 306 is horizontal and lies in a plane perpendicular to the plane of the first and second stand frame portions 302, 304, as illustrated. As shown, the second extendable stand frame portion 304 extends from a top end of the first fixed stand frame portion 302. A bottom end of the first fixed stand frame portion 302 is coupled with a base stand 308 provided with wheels 310. In an embodiment, a total height of the monitor stand 300 as illustrated in FIG. 3A in a fully extended position (from a bottom end of the wheels 310 to the top end of the monitor arm assembly 306) is approximately 62.1 inches. It should be noted, however, that the dimensions provided in this specification are provided as exemplary dimensions and that the apparatus of the present specification is not limited to the dimensions provided. The width of the monitor stand 300 measured from an outer end of wheel 310 a to an outer end of the wheel 310 b is approximately 25.4 inches.

FIG. 3B illustrates the monitor stand 300 partially dismantled, in accordance with an embodiment of the present specification. In an embodiment, in order to dismantle/fold the monitor stand 300, the monitor arm assembly 306 is rotated about the point of connection with the second extendable stand frame portion 304 such that the monitor arm assembly 306 occupies a plane parallel to the plane of the first fixed stand frame portion 302. In an embodiment, the monitor stand 300 includes first and second pins that pass through the coupling component 305 and the monitor arm assembly 306. When the pins are in a first inserted position, the pins fix the position of the monitor arm assembly 306 on the coupling component 305 relative to the second extendable stand frame portion 304. When the pins are in a second removed position, the monitor arm assembly 306 is free to either be detached from the second extendable stand frame portion 304 or to rotate with respect to it. In an embodiment, the monitor stand 300 further includes third and fourth pins that pass through the coupling component 305 and the extendable stand frame portion 304. When the third and fourth pins are in a first inserted position, the vertical position of the coupling component 305 within the extendable stand frame 304 is locked. When the third and fourth pins are in a second removed position, the coupling component 305 may be slid vertically along the extendable frame portion 304. The pins are shown in greater detail with respect to FIGS. 4D and 4E. In addition, the extendable stand frame portion 304 is refracted into the first fixed stand frame portion 302 and the coupling component 305 is slid to its second bottom position to dismantle the monitor stand 300 even further.

FIG. 4A illustrates another view of the monitor stand 400 in a dismantled configuration in accordance with an embodiment of the present specification.

The weights, as well as the dimensions, of the rigid frame portion 402, the monitor arm assembly 406, and the base stand 408 are such that the monitor stand may be easily transported after dismantling.

After such dismantling, the monitor arm assembly 406, the rigid frame portion 402 with the retracted extendable frame portion 404 and coupling component 405, and the base stand 408 may be packed separately. The dismantled parts may be transported by using a small to medium sized vehicle. In various embodiments, materials such as aluminum, steel and acrylonitrile-butadiene styrene (ABS) are used to manufacture the monitor stand of the present specification. The structure of the monitor stand is designed to withstand vibrations and remain durable.

In various embodiments, four pins are provided that enable the height of the monitor stand to change from that shown in the extended configuration of FIG. 3A to that shown in collapsed configuration of FIG. 4A. In an embodiment, each pin has a screw and nut mechanism that tightens the pin, thereby fixing a position of the coupling component 405 with respect to the extendable frame portion 404 or the monitor arm assembly 406 with respect to the coupling component 405. FIG. 4D illustrates a monitor stand 400 in a dismantled state, in accordance with an embodiment of the present specification. A portion of the monitor stand 412 in FIG. 4D comprises the coupling component 405, pins 414, 416, 418, 4120, and a peg 413 of the monitor arm assembly 406 for attaching the monitor arm assembly 406 to the coupling component 405 and adjusting the position of the coupling component 405 relative to the extendable frame portion 404.

FIG. 4E illustrates a magnified view of the section 412 on FIG. 4D. FIG. 4E shows pins 414, 416, 418 and 420 provided for attaching the monitor arm assembly 406 to the coupling component 405 and for adjusting the position of the coupling component 405 relative to the extendable frame portion 404. Specifically, pins 414, 416 are used for removably attaching the monitor arm assembly 406 to, and rotating it within, the coupling component 405. Pins 418, 420 are used to lock the coupling component 405 in a vertical position relative to the extendable frame portion 404.

With pins 414, 416 removed and the monitor arm assembly 406 dissambled from the monitor stand, a user may couple the monitor arm assembly 406 with the coupling component 405 by inserting peg 413 of the monitor arm assembly 406 into opening 407 of the coupling component 405. At this point, the monitor arm assembly 406 may be freely rotated within the coupling component 405. The peg 413 includes a plurality of openings for receiving pins 414, 416. In an embodiment, the peg 413 is cylindrically shaped and includes four openings or receptacles, each positioned in a same circular plane and 90 degrees apart from one another along an outer surface of the peg 413. The receptacles are configured to receive pins 414, 416. When the monitor arm assembly 406 is rotated such that it is positioned in a vertical plane parallel to the extendable frame portion 404, the two pins 414, 416 can be inserted through a first set of holes in the sides of the coupling component 405 and into two opposing receptacles on the peg 413, fixing the monitor arm assembly 406 in the vertical position for storage and transport. When the monitor arm assembly 406 is rotated such that it is positioned in a horizontal plane perpendicular to the extendable frame portion 404, the two pins 414, 416 can be inserted through holes in the sides of the coupling component 405 and into the other two opposing receptacles on the peg 413, fixing the monitor arm assembly 406 in the horizontal position, ready for the attachment of monitors.

With pins 418, 420 removed, the coupling component 405 is free to move vertically within a channel 411 of the extendable frame portion 404. Inserting pins 418, 420 through a second set of holes in the coupling component 405 and into the extendable frame portion 404 locks the coupling component 405 in a vertical position relative to the extendable frame portion 404. Referring to FIG. 4E, pins 418, 420 are in place and the coupling component 405 is locked in its second, bottom position and is ready for storage and transport.

FIG. 4F is a flow chart listing the steps involved in transforming a monitor stand from a stowed configuration, similar to that shown in FIGS. 3B and 4C, to an operational configuration, similar to that shown in FIG. 3A. Optionally, if the rigid frame portion is not attached to the base stand, a user inserts the insertion tab at the bottom end of the rigid frame portion into the opening in the base stand to couple said rigid frame portion with said base stand at step 430. Optionally, if the monitor arm assembly is not attached to the coupling component, a user removes the first and second pins at step 432, inserts the monitor arm assembly peg into the opening in the coupling component with the monitor arm assembly in the vertical position, and re-inserts the first and second pins, securely attaching the monitor arm assembly to the coupling component. At step 434, the user removes the third and fourth pins, slides the coupling component to its first, top position or another vertical position along the channel within the extendable frame portion, and re-inserts the third and fourth pins. Then, at step 436, the user actuates a lever or button on the monitor stand to release the extendable frame portion from its locked position within the spine portion, extends said extendable frame portion upward into a higher vertical position, and releases said lever or button to re-engage the lock on the extendable frame portion. At step 438, the user removes the first and second pins, rotates the monitor arm assembly into a horizontal position, and replaces the first and second pins, locking the monitor arm assembly in a horizontal plane and readying it for monitor attachment. In other embodiments, the step of rotating the monitor arm assembly from the vertical position to the horizontal position may be done prior to extending the height of the coupling component and/or extendable frame portion, as long as care is taken to ensure the monitor arm assembly is high enough to clear the base stand during rotation.
